The IC CD4017 is used for counting applications, it has the capability to turn on 10 outputs sequentially in a pre-defined time and reset the count or hold it when required. It also has the capability to indicate the status of counting using Carry pin. This is commonly used for Led chasers and other logical output projects, so if you are looking for an sequential decoded counting IC that can count up to 10 then this IC will be your right choice

The IC can work from 3V to 15V, but normally powered with +5V to the Vdd/Vcc pin and the Ground/Vss pin is connected to ground. We have 10 output pins ranging from Q0 to Q9, these pins can be connected to any load but we are using LEDs here as shown in the circuit below.

Features:

• High speed 16 pin CMOS Decade counter
• Supports 10 decoded outputs
• Wide supply voltage range from 3V to 15V, typically +5V
• TTL compatible
• Maximum Clock Frequency: 5.5Mhz
• Available in 16-pin PDIP, GDIP, PDSO packages

Package: PDIP-8
